      Description

      Migration of the sessions catalog needs to be prepared to find a new transaction already started on the recipient shard for an older session it is migrating from the donor. Because of the place where this try/catch block is placed though, such a condition will skip all the sessions that follow, meaning that there will be incomplete session information on the recipient shard.
